According to foreign media reports, among all the planets and moons in our solar system, Saturn’s icy moon Enceladus seems to be one of the few satellites that may support some form of life. Although it has a hard ice shell, there is liquid water deep in the ice. And that’s because researchers saw it gushing out of a giant crack in the planet’s ice. < / P > < p > now, using data from NASA’s Cassini space probe, researchers have found signs of what they believe to be new ice not only in the active south pole of the moon, but also in the Northern Hemisphere – a new discovery. < / P > < p > the study, published in Icarus, used infrared spectrometer data to estimate the age of the ice around Enceladus. It is understood that new ice and old ice have different characteristics, and these data give scientists a good understanding of the time when ice formed. < / P > < p > to be honest, the first finding is not surprising: the south pole of Enceladus is completely covered with new ice. NASA has discovered this earlier, with large amounts of liquid water ejecting from cracks in the moon’s south pole. The water will freeze almost instantaneously, but most of it will eventually return to the Antarctic. < / P > < p > however, Cassini photographed all sides of Enceladus, and the researchers found that there was also a lot of new ice around the northern hemisphere. Although its density is far less than that of new ice near Antarctica, it suggests that the northern hemisphere of Enceladus was active in the near past. < / P > < p > based on current observations, it is difficult to say how these new ice reached the northern hemisphere. It either has an activity similar to that in Antarctica, where cracks form and then gush out, or it is a more gradual process in which water seeps out of smaller holes over time. < p > < p > Gabriel is the co-author of the study Tobie said in a statement that infrared shows that the surface of Antarctica is very young, which is not surprising because they already know that there are jets of ice material flowing there, and now thanks to these infrared eyes, humans can go back to the past and say that a large area of the northern hemisphere also looks very old on the geological time line, and it is likely to have been active not long ago.
